CHARLOTTE, N.C. — When you get ready for the day or get ready before bed, you might reach for the toothbrush first. But be honest — how often do you actually change your toothbrush?
According to the American Dental Association (ADA), 69% of Americans brush their teeth twice a day, which means those toothbrushes are getting a lot of use. But when should you throw the old one away?

WHAT WE FOUND:
The ADA recommends replacing your toothbrush every three to four months, or more frequently if the bristles are matted or frayed.
However, both Clemons and experts from The Silberman Dental Group suggest that if you’ve had a bacterial infection like strep throat, it might be worth getting rid of your toothbrush after you recover.
“Most healthy people are probably at a very low risk of reinfecting themselves from something they’ve already built an immunity to,” Clemons explained. “But it’s kind of one of those ‘better safe than sorry’ situations.”
The American Medical Association adds that bacteria like strep throat can survive on surfaces for a period of time. For those with weakened immune systems, there could be a risk of reinfection from using the same toothbrush.
So experts say, when in doubt, throw it out.
